Unable to push/pull from GitHub Desktop after adding SSH key to account

Description

Version

• GitHub Desktop: 1.6.4

• Operating system: macOS Mojave, 10.14.3

Steps to Reproduce

1. Opened up GitHub Desktop, which automatically puts me in the one repository I use it for.
2. Click “Fetch origin” (currently says “Never fetched”, however I did a pull this morning and everything works)
3. Get the following error:

Authentication failed. You may not have permission to access the repository or the repository may have been archived. Open preferences and verify that you’re signed in with an account that has permission to access this repository.

1. Open “Preferences”—I am indeed signed in.
2. Switch over to the web client and check the repo “Settings”. Permissions work.

Expected Behavior

It’ll pull from origin with no issue

Actual Behavior

It doesn’t

Additional Information

I added an SSH key to my account moments before this happened and set up my remotes in the CLI so I could switch between the CLI and the GUI in order to help a colleague troubleshoot an issue. Checked to make sure there was nothing in staging and that I was working on the latest version of the file, and everything was fine and up-to-date. But once I was able to set up the remote and push to origin with my ssh key, I was then unable to do anything in the GUI.

For people ending up here: I changed from ssh to https in GitHub Desktop and it worked!

I was facing the same issue. Now fixed. basically, the config file was missing for me "If you’re using macOS Sierra 10.12.2 or later, you will need to modify your ~/.ssh/config file to automatically load keys into the ssh-agent and store passphrases in your keychain."

I followed these steps
